Just to throw it in there, http://www.opanda.com/en/iexif/
is a nice exif plugin that works with both IE and firefox (with an additional extension for FF, its simple enough to install). I know I got bored of downloading images to then check exif info, I love this plugin.
Also to the OP, the book mentioned seems to be one of the best for layman reading. It helped me relearn all that stuff Id forgotten from h.s. photography classes in a few days. For the price, great read.
